LENNOX HEARTH PRODUCTS Rhapsody™
model fireplaces are direct-vent (top vent
only), sealed combustion, air-circulating gas
fireplaces designed for residential, manufac-
tured home and commercial applications.
Direct-vent appliances operate with the com-
bustion chamber isolated from the indoor
environment. All air for combustion is brought
in from the outside, and exhaust gases are
vented through the same direct-vent, coaxial
(intake/exhaust) vent system.
These appliances are designed to operate
on natural or propane gas
only
. The use of
other fuels or fuel combinations will degrade
the performance of this system, may be
dangerous, and may void the warranty.
The electronic system is switchable between
standing and intermittent pilot modes
(see
Figure 15)
.
The Total Comfort Control™ Remote Control
System is included with all models and provides
remote operation of several fireplace functions
(manual adjustment of the gas valve settings is
not possible).
See
Page 26
for details.
Electrical power (120V AC line voltage) is rec-
ommended to operate the fireplace; however,
“AA” batteries can be used for full-time opera-
tion or as a backup in case of a power outage.
Note: Batteries will operate the gas valve
OPEN/CLOSE and pilot ON/OFF functions
only. Electrical power (120V AC line volt-
age) is required to operate the following
optional components
(bat teries will not
power any of these options):
• Blower Kit
• Power Vent System
• Panel Backlighting Kit

WEALTH Of MASSACHUSETTS
These fireplaces are approved for installation in
the US state of Massachusetts if the following
additional requirements are met:
• Install appliance in accordance with Massa-
chusetts Rules and Regulations 248 C.M.R.
• Installation and repair must be done by a
plumber or gas fitter licensed in the Com-
monwealth of Massachusetts.
• The flexible gas-line connector used shall
not exceed 36 inches (92 centimeters) in
length.
• The individual manual shutoff must be a
T-handle type valve.
Massachusetts Horizontal Vent
Requirements
In the Commonwealth of Massachusetts, hori-
zontal terminations installed less than seven
(7) feet above the finished grade must comply
with the following additional requirements:
• A hard-wired carbon monoxide detector
with an alarm and battery backup must be
installed on the floor level where the gas
fireplace is installed. The carbon monoxide
detector must comply with NFPA 720, be
ANSI/UL 2034 listed and be ISA certified.
• A metal or plastic identification plate must
be permanently mounted to the exterior of
the building at a minimum height of eight (8)
feet above grade and be directly in line with
the horizontal termination. The sign must
read, in print size no less than one-half (1/2)
inch in size: GAS VENT DIRECTLY BELOW.
KEEP CLEAR OF ALL OBSTRUCTIONS.
COLd CLIMATE INSULATION
REqUIREMENTS
For cold climate installations:
• Use noncombustible caulk to seal all joints
around the appliance and wherever cold air
could enter the room.
• Caulk all gas-line holes and other openings
(or stuff with unfaced fiberglass insulation).
• Caulk firestops only where pipe penetrates
an outside wall, attic, or other other uncon-
ditioned space.
• If the floor is above ground level, insulate
the outside chase cavity between the studs
and under the floor beneath the appliance.
• If installing the fireplace on a cement slab,
place a sheet of plywood or other raised
platform underneath to prevent cold transfer
to the fireplace and into the room.
• Drywall and tape all inside sur faces of sur-
rounding chase for maximum air tightness.
